    scripts: bitbake-metadata2doc.sh: use a fresh build directory

    Before this change we were using a hardcoded build directory
    ("build").  That approach could lead to problems if the build
    directory already existed and contained settings other than the
    default ones (setup-environment would not overwrite conf/local.conf
    and/or bblayers.conf).

    This patch changes that by creating a fresh build directory, thus
    making setup-environment create new configuration files with the
    default settings, which will make scripts generate more deterministic
    results.

    scripts: list images and packagegroups from fsl layers

    Generate release-notes/source/images.inc and
    release-notes/source/packagegroups.inc based on recipes in
    meta-fsl-arm, meta-fsl-arm-extra and meta-fsl-demos.

    The "heuristic" to determine what is an image/packagegroup is pretty
    lame: it just checks if the recipe name contains `image' or
    `packagegroup'.

    The generated files contain an rst list mapping the image and
    packagegroup recipe names to their corresponding descriptions.

    The generated files (.inc) have intentionally not been added to this
    commit.
